Residents in Portsmouth can look forward to a warm and sunny spell of weather starting early next week, following a windy and overcast Easter weekend. According to the Met Office, the city will largely avoid the severe conditions brought on by Storm Dave, which is currently set to impact northern parts of the United Kingdom with high winds.

The local weather for the remainder of the weekend will be breezy, with gusts reaching 42mph. Saturday, 4 April 2026, is expected to remain overcast with a high of 14°C. Sunday, 5 April 2026, will see sunny intervals and a temperature of 13°C, though there is a 70% chance of light rain around midnight.

Conditions are set to improve significantly from Monday, 6 April 2026, as sunny weather takes hold. While the morning may start chilly at 4°C, temperatures will climb to 13°C throughout the day. The warming trend continues on Tuesday, 7 April 2026, with forecast highs of 18°C, and peaks on Wednesday, 8 April 2026, when temperatures are expected to reach 19°C.

Those planning to enjoy the outdoors should be aware that the Met Office has forecast very high pollen levels from Monday through Wednesday. While Storm Dave will cause significant disruption in northern regions, including potential gusts of 80-90mph in exposed Scottish locations, Portsmouth is expected to remain much drier with only light, passing showers.
